   item        is an item which may or may not be an element of 
               the input set. 
 
 
   set         is a CSPICE set.  set must be declared as an integer

   1) If the input set argument does not qualify as a CSPICE set, 
      the error SPICE(NOTASET) will be signaled.  CSPICE sets have
      their data elements sorted in increasing order and contain
      no duplicate data elements.

   2) If the input set does not have integer data type, the error
      SPICE(TYPEMISMATCH will be signaled.
